METHOD 0F HUMIDIFICATION.

Specification of Letters Patent. Patented June 24, 1919.

Application led`February 4, 1918. Serial No. 215,416..

To all whom t may concern! Be it known that I, LEE H. PARKER, a citizen of the United States, and aresident of Boston, in the county of Suffolk and State of Massachusetts, have invented: an in Methods of Effecting Humidification, of which the following description, in connection with the accompanying drawings, is a specification, like.

characters on the drawings -representing like parts. i

This invention relates tomethods for effecting humidification for various purposes, as, for example, in dwelling houses, I mlls and plants of various types and descriptlons.

In order that the principle of my1nven tion may be readily understood, I will set forth one form of means for practising the same, but without in any way llmitlng myself to the use of such means in carrylng out the method.'

and maintain a `film of the liquid that is ern-f ployed for humidification pur-poses and which preferably is water, and I discharge the material of said film into the surrounding air by subjecting such film to the impact of a film breaking and discharging Huid, which is preferably air, but which may be any other suitable medium. Preferably such film is subjected to the impact of the film breaking and discharging fluld in a direction ytransverse to the film.

The method may be carried out'by many different types of nozzles or other devices, but for convenience of description I shall describe in detail a nozzle by which such method is most effectively carried out.

Referring more particularly to'the drawing, I have therein represented a nozzle preferably composed of a body 1 having a passage 2, into whlch water 1s adapted to be drawn through the passage 3 from any suitable source. The water is preferably admitted under low pressure. Air or other suitaJble medium is admitted under pressure through a passage 4 from any suitable source. The body 1 of the nozzle has a partit-ion 5', thus providing a substantially axial passage .'for the air, and which is in communication with the air supply pipe 4, the entering air and water thus being separated 'by the partition 5. Within the said passage partition 5. -Tfhe water passage 2 communi cates with the water supply passage 3, and upon the o uter end of the nozzle is adjustably. secured by screw threads or otherwise a cap 12 having a centralA discharge opening 13 in axial alinement with the opening 14 in the cap-like mein-ber 11. The construction is such that the air under pressureentering through the 'passage 4 causes waterto be drawn into the passage 3. .The watei'constantly forms a film Ibetween theiner surface of the cap 12 andthe outer surfaceof the cap-like member 11, and thefthickness of. such film may be readily'varied` fby adjustment of said cap 12. uch film isconstantly formed and maintained by capillary action `between the two cap-like members 11, 12, which are brought close enough to-` gether to insure such action. The air entering through the passage 6 breaks through thefilm at the central portion of the cap and dischargesthe same in very fine globules into the surrounding air and effects the desired humidification thereof. Such film is constantly broken by the air or other suitable fluid, but is constantly restored through the action of capillarity, hence the water may be merely under suc tion due to capillary action.

The water or other liquid is maintained as a film between the two cap-like members 1'1 and 12. The water from which the film is formed is supplied at a comparatively low velocity, and the stream of air entering through the axial passage 6 at high velocity tears apart the water film and drives the sa-me through the opening 13 in the cap 12. As the stream of air issues from the opening 13, it expands and thus forms a conical mass orfilm of thoroughly atomized water. If the nozzle be placed near an air entrance in the room or building, the atomized water practised, it is clearly to be understood that the method may be carried out by any suitable means, and that it is not dependent upon any particular form or structure of mechaf msm. f

Having thus described one form of means whereby my method may be carried out, it is clearly torbe understood that although specific terms are. employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being'. set forth in the following claims.

Claimss l. That method of effecting humidification which comprises conducting by capillarity a film of water between two surfacesso nearly in contact as to establish a film of water by capillarity therebetween, propelling a lfilm breaking and dischargin fluid substantially transverseto the esta' lished film, effecting the breaking and discharge of said film by the action of. the propelled fluid and Afinally effecting the humidification of the air into which the material of kthe film is discharged.

2. That method of effecting humidification which comprises conducting-by capillarity a film of water between two surfaces so nearly in contact as to establish a 'film by capill-arity therebetween, disrupting said film bydischarging a film breaking stream of air under pressure substantially transverse to and' against the established y-film and finally effecting the humidification of the air into which the material of the film `is dischar ed. .j

3. gIhat method of effecting humidification which comprises conducting by ca illarity a? film of water between 'two sur aces so nearly in contact as to establish a film by capillarity therebetween, propelling air under pressure against said film and substantially transverse thereto so as to break and discharge the Ifilm, continuously effecting the re-establish'mentof said film by capillarit)7 and continuously effecting the humidification of the air into which the material in the material of said broken film is dis charged.

5. That method of effecting humidi-fication which comprises conductingA by capillarity a film of water into a position substantially transverse to the path of a current of compressed air, effecting breaking and discharge of said -film by the action of said compressed air and effecting the ensuing humidification of air by. permittin and effecting the discharge of the material of the film into said air.

In testimony whereof, I have signed my name to this specification.
